Re: a mobile phone that you only have to charge once a week rather than twice a day
"Of course it's a Nokia C6-01 with the Qt remake of Symbian."
You have a phone.
The rest of us have a high powered pocket computer with always-on network connectivity that happens to make phone calls (but in fact hardly ever does so). And I can remember when _those_ were both bulky and only lasted an hour or less on rechargable batteries. (I'm not referring to Psions here)
